    Subject[PATCH 2/3] ARM: dts: at91: sam9x60ek: classd: pull-down the L1 and L3 lines
    Date
    The L1 and L3 lines drive NMOS transistors that are OFF with a low level.
    On the SAM9X60 EK board, if the pins corresponding to L1 and L3
    have pull-ups enabled, there is an extra 2 x 30uA power consumption.
    Use pull-downs for these 2 lines to remove the unnecessary power
    consumption.

    Fixes: 1e5f532c2737 ("ARM: dts: at91: sam9x60: add device tree for soc and board")
